Chou cream puffs are the most popular item here. The secret behind the success is the use of cultured butter, which is famously difficult to control the temperature of. By keeping strict control of the storage environment even as far as their wholesale suppliers, they can prevent the butter from becoming sour, allowing the unique flavours of “Kashinoie” to fully blossom. Aside from the delicious flavours, Kashinoie is also famous for the huge 12cm round “1000 yen Chou cream”.
